User Settings

BackgammonDB's settings let you tune how mistakes are classified, how the board looks, and how the review screen is laid out. They're saved in your browser and follow you across sessions on the same device.

Error bands

These thresholds decide how a move's equity loss is classified — and they drive the Errors / Blunders / Howlers filters and counters throughout the app.

Setting	Default	What it does
Error threshold	−0.020	Equity loss at which a move counts as an error (the XG-standard 2 milli-equity line).
Blunder threshold	−0.080	Equity loss at which a move becomes a blunder. The bands between error and blunder (doubtful, bad, very bad) divide the gap evenly.
Howler threshold	−0.250	Equity loss at which a blunder escalates to a howler.
Nav error threshold	−0.020	A separate threshold used only by the Alt+Arrow jump-to-error navigation, so you can hop only between severe mistakes or stop on every imperfect move. Its magnitude can't exceed the howler threshold.
Joker threshold	0.300	The luck swing on a single roll above which it counts as a joker (lucky) or anti-joker (unlucky). Shared with the Luck section and the action-list joker column. See Performance Rating.

Display

Setting	Default	What it does
Equity display	Equity	Show raw equity values (e.g. −0.025) or percentages (−2.5%).
Board theme	Midnight	The board's color scheme; changing it recolors the board live.
Board orientation	Bear off right	Mirror the board so bear-off is on the left instead. Also toggled with the F key. (The V key is separate — it flips the perspective to view from the opponent's side.)
Collapse transitory moves	On	Render a checker's path as a single hop ("20/13" instead of "20/18/13"); intermediate landings that hit are always kept.
Good-move indicators	Off	Show a green marker on correctly-played moves, not just on mistakes. See Action List & Filtering.
Joker column	Off	Add a column to the action list marking lucky/unlucky rolls with a clover icon. See Action List & Filtering
Hide best overlay when correct	On	When your played move was good (within the error threshold) — not just when it was the very best — suppress the dashed best-move overlay so the solid played arrow stands alone.

Review layout

Toggles for the match-review screen — each also has a keyboard shortcut and remembers its state.

Setting	Default	What it does
Action sidebar	Open	The action-list sidebar (key: [ ).
Progression graph	Closed	The match-progression graph dock above the board (key: H).
Candidate strip	Open	The per-action candidate moves below the board (key: ] ). Desktop and mobile keep independent open/closed state.
